What type of advertisement is a commercial that pops up while streaming music classified as?

The correct classification for a commercial that appears while streaming music is broadcast advertising. This is due to the method of communication it employs, as it reaches audiences through digital channels that deliver audio-visual content.

Broadcast advertising encompasses various formats transmitted over the airwaves or through internet platforms, allowing for the dissemination of messages to a broad audience. In the context of streaming music, it aligns with audio broadcasting, wherein the advertisement interrupts or plays alongside the music, capturing the listener's attention.

Other advertising types, such as digital app, outdoor, and print have distinct characteristics that do not apply to the streaming music context. Digital app advertising typically refers to promotions displayed within mobile applications, outdoor advertising involves physical media placed in public spaces, and print advertising is associated with tangible media like newspapers and magazines. Therefore, the classification of the streaming music commercial as broadcast recognizes its method of reaching consumers through audio channels.
